Driving with an Arduino? Keep the lane!

Abstract

Abstract The Arduino is a popular and useful tool in STEM and physics education. Teacher demonstrations, laboratory and home work are supported by an incredibly wide range of application examples for a low cost. Since the heart of the Arduino board is an industrial microcontroller, it is a good chance to teach the basics of the related rules, standards and engineering-like approach of an application that is essential in high quality STEM education. We discuss here the output drive capability often misinterpreted in the Arduino community and we also draw attention to the importance of developing the right attitude.
